The brightest star in Perseus is [6453] alpha Persei, also known by its traditional names Mirfak ("elbow") and Algenib ("the side"). Mirfak is a yellow-white supergiant lying approximately 590 light-years from Earth.
The brightest star in the constellation, second-magnitude Alpha Persei, has two alternative names. One is Mirphak (or Mirfak), from the Arabic for ‘elbow'.
The easiest way to find them is to form a triangle, using gamma Andromedae and alpha Persei. Then the northern point becomes the twin clusters.
For example, Alpha Persei is classed as F5 Ia, which means that it falls about halfway between the beginning of type F (i.e., F0) and of type G (i.e., G0). The Ia suffix means that it is a particularly luminous supergiant.
star lies in the west central part (3:8:10.1+40:57:20.3, ICRS 2000.0) of Constellation Perseus (see chart and photo), the mythical Greek Hero who uses the Gorgon Medusa's severed head to change Cetus into stone -- southwest of Mirfak (Alpha Persei).
